ReviewManagement Strategies for Severe Respiratory Failure: As Extracorporeal Membrane Oxygenation Is Being Considered.
Pulmonary and critical care physicians must be facile in recognition and management of patients with acute respiratory distress syndrome (ARDS). Part of the current critical care knowledge base must include an understanding of how extracorporeal membrane oxygenation fits into the paradigm of ARDS management without using it as a "salvage therapy." This article provides a basic understanding of the evolution of ARDS to multiple organ dysfunction syndrome, recognizing benefits and limits of rescue therapies, indications and contraindications of extracorporeal membrane oxygenation, and coordination of care for severe respiratory failure.

There is a current trend towards lighter or no sedation of mechanically ventilated patients in the intensive care unit. The advantages of less sedation have been demonstrated as shorter duration of mechanical ventilation and reduced length of stay in the intensive care unit and hospital. Non-sedated patients are more awake during mechanical ventilation, but little is known about how this affects the intensive care patient. ⋯ Being awake during mechanical ventilation entailed new opportunities and challenges for critically ill patients. Patients found themselves at the interface between agency and powerlessness as they were able to interact, yet were bound by contextual factors such as bodily weakness, technology, spatial position and relational aspects. This knowledge is important to develop patient-centered nursing practice in the context of lighter sedation.

Lung Injury Etiology and Other Factors Influencing the Relationship Between Dead-Space Fraction and Mortality in ARDS.
In ARDS, elevated pulmonary dead-space fraction (VD/VT) is a particularly strong indicator of mortality risk. Whether the magnitude of VD/VT is modified by the underlying etiology of ARDS and whether this influences the strength of its association with mortality remains unknown. We sought to elucidate the impact of ARDS etiology on VD/VT and also to determine whether ARDS severity, as classified by the Berlin definition, has correspondence with changes in VD/VT. ⋯ VD/VT magnitude varies by ARDS etiology, as does mortality. Only in mild ARDS does VD/VT fail to distinguish non-survivors from survivors. Nonetheless, VD/VT has the strongest association with mortality risk in those with ARDS.

Mechanical ventilation weaning protocol improves medical adherence and results.
Implementation of a weaning protocol is related to better patient prognosis. However, new approaches may take several years to become the standard of care in daily practice. We conducted a prospective cohort study to investigate the effectiveness of a multifaceted strategy to implement a protocol to wean patients from mechanical ventilation (MV) and to evaluate the weaning success rate as well as practitioner adherence to the protocol. ⋯ A multifaceted strategy consisting of continuing education and regular feedback can increase physician adherence to a weaning protocol for mechanical ventilation.

Assessment of mechanically ventilated patients intoxicated with organophosphates by a novel surface electromyographic index.
We present a new electromyographic index, named Engagement of Respiratory Muscle (ERM), for assessing the level of participation of respiratory muscles during spontaneous breathing test in patients poisoned with organophosphorus compound. ⋯ The ERM is a promising index to assess the level of participation of respiratory muscle on spontaneous breathing test in patients poisoned with organophosphorus compounds, which could improve the extubation prognosis for these patients.
